STEAIVMGENERATOR.

SPECIFICATION forming part of Letters Patent No. 680,736, dated August20, 1901. Application filed December 24,1900. Serial No. 40,929. (Nomodel.)

To all whom it may concern:

Be it known that I, GEORGE E. RIBLET, a citizen of the United States,residing at Erie, in the county of'Erie and State of Pennsylvania, haveinvented certain newand useful Improvements in Steam-Generators; and Ido hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to steam-generators and it consists in certainimprovements in the construction thereof, as will be hereinafter fullydescribed, and pointed out in the claims.

The invention comprises two leading features: first, the moving of steamor water in a reversed current to that of the heated gases, so as todeliver the hottest steam of which the device is capable, and, secondly,to form a steam-generator in two compartments, one for the water and theother for the steam, and arranging means for subjecting the water to apressure that will largely prevent steaming in the water compartment andfor maintaining the other compartment at a pressure below which thewater will steam at the temperature at which it is subjected in thefirst compartment, so that water passing from the compartment having thegreater pressure will immediately be converted into steam. These leadingfeatures are also combined and my invention also consists of otherfeatures and details, which will hereinafter fully appear in thedescription and claims.

The invention is illustrated in the accompanying drawings, as follows:

Figure 1 shows a section on the line 1 l in Figs. 2 and 3. Fig. 2 showsa section 011 the line 2 2 in Figs. 1 and 3. Fig. 3 showsasection on thelines 3 3 in Figs. 1 and 2.

The shell A of the generator is preferably made in two sections. Itsimply incloses the steaming devices and directs and confines the heatedgases. Arranged in the upper end of the case is the Water-chamber B.This rests, preferably, on the lugs a in the case. The chamber isprovided with the shell I) and the fines b. In fact, this chamber issimilar in construction to an ordinary upright boiler. Immediately belowthe chamber B is a second chamber 0, formed by the shell 0 and havingthe fines c therein. It is similar in construction to the chamber B andrests upon lugs a, similar to the lugs a If desired, the number of thesechambers may beincreased. Connected with the upper chamber is a feed-Water pipe E, and connecting the upper part of the chamber B to thelower part of the chamber 0 is a pipe F. The purpose of so connectingthe two chambers is to prevent circulation between them. Extending fromthese upper chambers are the pipes P, which pass to an ordinarysafety-valve P. EX- tending from the chamber 0 is an outlet-pipe Gr. Thepassage through this pipe is controlled by a valve g, the stem g ofwhich extends out through the case A, so that the valve may be operated.The pipe G passes into a manifold 1-1. This manifold is formed insections, which are clamped together by means of a bolt h extendingthrough the center of the manifold. Connected with each section of themanifold is a pipe I. It preferably has several loops or coils, and theypass into the manifold J, which is formed of a series of sectionssecured together by a boltj extending through the center of the section.Passing out of the manifold is a steam-pipe K. The burner Q is arranged,preferably, below the manifold J. Any desired burner or ordinary furnacemay be used. Extending between the loops or coils are a series ofdeflectors a for directing the heated gases by the pipes I. It will benoted that the heated gases nearest the fire contact the outgoingportion of the steam-pipe and that the current of the heated gases as itpasses through the generator is in a reverse direction to that of thesteam passing out of the generator and that the water-chambers, whichare in one sense generators, are also reversed in this same order, sothat the hotter gases contact the chamber nearer the steam-outlet. Bythis arrangement the waterin the chamber G is maintained at a highertemperature than that in the chamber B, and the steam as it passes alongthe coil I is superheated to the highest degree possible by thearrangement of the reverse currents thus described. A pipe L also isconnected with the steam-supply, preferably with the generator, andpasses to a steam-pump M. This pump comprises the cylinder M andpump-chamber M The pump-chamber has the usual intake-pipe N,

and the pump has the ordinary valve and incident mechanism. The pump isarranged for direct action and the steam-piston is of asufficientlylarger area than that of the pumpplunger to elfect thedifference in pressure desired between that maintained in the steampipesI and the chamber 0.

By the mechanism so arranged the water in the Water-chamber ismaintained at a pressure which will largely prevent steaming in theWaterchambers at the temperature at which they are subjected. At thesame time the Water in the said chambers is heated to such a point thatit will immediately pass into steam on being delivered into the pipes Iat the smaller pressure maintained in the said pipes. In this respectthis generator is distinguished from that class known as flashboilers inthat the steam is generated not so much by immediate contact with thewalls of the pipes I as by the difference of pressure maintained in thepipes I and the waterchamber. The steam as it passes through the coilsis superheated. Of course an important feature is that there should be adifference of pressure in the chambers O and the coils I and that thewater be heated, so as to steam somewhere between those pressures. Asthe pressure is increased the temperature may be increased.
